ATT EY Patented Aug. 30, 1932 'PATENT OFFICE- ROGER W. CLIFFORD, orscHnNn'crAnY, NEW YORK LATERAL 'Morroiv DEVICE l' Application4ledseptember 24, 1930. Serial No. 483,999.

In supporting theback end of a locomotive, it has beenthe practice toemploy a four wheel trailing truck. Such trucks, while having anincreasedcarrying capacity over that E of two wheel trucks Yby reason ofthe additional'axle, may be so constructed as to avoid any substantialincreasein friction between the-flanges of the wheels andthe rails whencurved sections of track are lpassed over.

.IU'Thisis .accomplished by employing means forv permitting one set ofwheels and their axle to have a lateral movement with relation tolthe'truck when travelling over the curve.

A truck ofthisfcharacter is described in U. S.

The object of the'present-invention is to provide an improved means forpermitting the aforesaid lateral movement of the wheels andl their axlewhile the truck is passing over the curved section ofthe track andeffecting an adjustment of the axle rand wheels back' to their normalposition after such section khas been passed over. f

All and anyjchanges inthe details of construction ,of the vspecificembodiment of the invention hereinafter exemplified which may provedesirable v and be apparentto those skilled in the art, are contemplatedas a part of this invention, within the spirit and scope ofthe appendedclaims. While the device claimed herein `is particularly adaptable foruse on a' four wheel trailing truck of the type aforementioned, rit willof coursebe understood-that the invention is adaptable for use inlanycase where the lateral adjustment of an axle and its wheels is desired.

In the accompanying drawing Figure 1, is

a side elevation cfa journal box with the invention applied thereto;Fig-2, isan end view of the same; Fig. 3, is a longitudinal sectiontaken on the line III- III ofrFig. 2;

Fig. 4, is a vertical section,the left side being taken on the lineIV-II/Iof Fig. 3, and the right side onv the line IV-IV of Fig.' 3;

Fig. 5, is a part plan view, its upper half being a horizontal sectionon'the line V-V of Fig. 1; and'Fig. 6, is a front view'of the outer` 5cspring seat. f

Referring inV detail to the drawing, the

journal 1, is positioned in a journal box 2, which is secured to thetruck frame by any convenient means such as the pedestals 3 (Fig.` 5).In accordance with the practice -well lmown in the art, the journal box2, is

left open at its inner end to receive the journal. A flange 4 is formedon the inner end of the journal box and is provided with a groove 5 inits outer side in which is mounted a wearing face 6 for the hub face 7of a wheel mounted on theaxle adjacent lits ournal. The journal boxes 2,(only one being shown) are so spaced with relation to the wheels on theaxle that their respective wear ing faces 6 will be a limited distancefrom .o5 the respective hub faces 7 of the wheels when the ysame are intheir normal' position, so that upon passing over a curved section oftrack, the wheels will be permitted a predetermined amount of lateralmovement, more particullarly the said distance between the wearingAfaces on the journal boxes and the hub faces of the wheels. An inwardlyprojecting flange 8 is formed on the inner sides of the journal boxesand is spaced from the inner side of the flange 4 so as to provide agroove 9 in "which a dust guard 10 is held. The dust guard surrounds thejournal and serves to protect the interior of the journal box from dustor foreign matter. Beneath the upper V`side of the kjournal box a wedge11 is positioned, said wedge having a longitudinal groove-12 formed inthe bottom of same. A bearing 13 of standard construction is disposed4above the journal, its upper side being wedge-shaped and engaging withgroove 12 of the wedge. In the usual manner the bearing 13 is heldagainst inward lateral movement by projections 14 formed on the innerwalls of the journal box; and by means of an upwardly extending flangeon the inner end of the bearing 13 andra lug 15 formed on the upperinner wall of the journal box, the wedge 11 is secured against lateralmovement in either direction and the bearing 13 against outward lateralmovement, the wedge 11 and bearing 13 being adapted upon the raising ofthe journal box away from the journal, to be laterally withdrawn fromthe said journal box. 10o

formed inwardly projecting gibs 17';` and` strengthening ribs 18 .are`formedon the lower outer wall of the journal box and tlielower" side ofthe sleeve, integrally therewith.. The

middle rib 18 is provided with aL flange 19` extending to one side ofsame. A spring 20 is disposed within the sleeve 16 and an outer springVseat121 is provided therefor. n l outer seat 21 is circular inshapeandof such dimension as to-be yable to horizontally pass-iybetweenthe gibs '17 to rest aga-inst the outer end of the sleeve.

heldin 'position thereby. An-outwardrly ex tending arm 23 is formedonthe said seat and adapted to secure Y the samein its `aforesaid engagedposition by meansof abolt 24 passed through saidarmfa-nd the flange 19and securedinplace by nut 25. Atfth'e inner endi ofthe sleeve a springseat 26'i's slidablydisposed,d the' said? seatcomprising a 'cylindrie'cal body 27 out away at itsv upper/side so as to 'litv in said sleeveand closed at its Outer end by a circular wall 28 also having' the up-Mper partfof its circumference vflattened to =c0r=- respond with theshape Aof the sleeve.v The 1in-I ner'springseat is formed with a recess29'.

the sleeve i and the yspringseats yis securedto4 theouter spring seatbya nut 311, whereby the seats yareheldfin a laterally adjustedpositi'onv against thespring 2.0 at a-.suitable normal ten-l`Selon. Itrwill be apparent that the'spring 20,

together with the outer and inner spring seats 21 nd26, and the bolt 30,may be removedas a lunit Vsimply by removing the bolt 24 and.'y

turningthe outer seat 21- so as to disengage' the projections 22from thegib 17, andwith-l drawing the said'` parts outwardly throughy thesleeve.
